Motor sport wiring not mil-spec wiring

[@x86FTW]

@52:12 Rob explains the greater number of strands / diameter of a wire increases it's voltage capability, and prevents the voltage from dropping. Technically speaking that's incorrect, the gauge of the wire increases its current handling (amp) capability, not voltage. Using a wire that is too small for the rated current will act more like a resistor and develop a voltage drop (lost as heat) that will subtract from the full potential of the rail, hence a lower voltage reading from the receiving end.

[@RobDahm]

At very high current loads the insulation can combust and light car interior on fire burn car to the ground! I’ve seen it happen unfortunately mainly in car audio, bad grounds spell disaster as well.

[@ruikazane5123]

Only thing that multi-strand wires are really important would be AC power transmission. AC tends to travel on the "skin" of the strand so having more of them helps that. Otherwise the strands are for flexibility alone. On DC power that doesn't matter.

It's also good to see the new hood and fenders coming along nicely. Since these have actually been handled by professionals in the industry, they should actually stay on the car during hard pulls. Also, whenever you get the wiring harness in, you'll have to print off a picture of the 4-rotor on a piece of shrinky-dink plastic sheeting just so you can shrink your car like all those harness boots. Also, at what point does Rob commission a polycarbonate dash and center column so he can admire his wiring loom while driving?

I design electrical systems and harnesses for collection vehicles and it always interesting to see other peoples perspectives about it. Keep the long format! Edit: Nice to see you're a TE man as well, they're a little expensive but the quality is always great.

[@joer8854]

There's a lot of things where you think that the extra expense isn't worth it until you use it and figure out why they charge that much. Working for GM I thought it was stupid that they use Torque angle Yield ratchets that cost 50 grand to well over 150 grand until the guy showed me that they perfectly set every bolt and nut and can sense the exact point when the bolt stretches too much. You wouldn't think it would matter that much but in a manufacturing setup it absolutely does. Beefy, they never break, endure constant abuse and work perfectly every single time. Zero downtime due to them. Set it and forget it.

I'm a robotics and automation engineer. I use Amphenol connectors almost everyday, which are basically the aerospace version of those connectors that you have for the Motorsport application. They're in some cases triple shielded for radio interference in signal level cases, but you can repurpose them with a different type of pin and socket to safely conduct high amperage as well. I have a tool at work that has 16 zones of 1,500 watt heaters. That's 24,000 watts continuous power that I can safely pull through one of these. But they also have thermal couples that report the temperature at signal level that are side by side the high power draw. So I have to intrinsically isolate the signals from the current carrying conductors. I run all 32 of these circuits through the same Amphenol connector, and never had a problem.

18:10 you don't need wasted wire (if the number of wires gets ridiculous) you can just use dummy wire. Inquire if the manufacturers sell it, if not, buy it from whomever makes it. It's the same material as the sheath of the wire you use, just no core, pretty cheap, last i checked. I stopped using it when i realized i can use fishing wire to fill out any layers (i use layers to separate various functions of the wire itself + sheets of aluminium to shield them) that are empty. It also increases the strength of the loom. Most of my core wires are 500 kg fishing line or if they really need to be structural cables, a steel strand core.
